The Sony BDP-S570's Blu-ray image quality is very good overall, image quality enthusiasts will find some minor issues. Yes, we'd rate the LG BD570 as marginally better, and the Oppo BDP-83 slightly superior to both, but the differences are tough to see even when you're looking for them, let alone when you're lost in a movie. We think nearly all buyers will be satisfied with the BDP-S570's image quality.
All our testing was conducted via HDMI at 1080p/60, with the Sony Bravia KDL-55XBR8 display and Oppo BDP-83 and LG BD570 for comparison. If your display supports and correctly handles 24 frames per second output (also known as 1080p/24), you can largely ignore these tests as we find all players to have virtually identical 1080p/24 performance. For more information on our testing procedure, consult our full guide to how we test Blu-ray players. Home theater enthusiasts can also see more detailed testing results in our 2010 Blu-ray players comparison chart.

Although the BDP-S570 has plenty more "pass" boxes than the competing LG BD570 on our detailed comparison chart, we'd actually prefer LG's performance overall. Yes, the Sony technically does better on cadence tests and text overlay on film, but we find those tests rarely make a difference in actual program material. On the other hand, the BDP-S570 failed one of the video resolution tests, and it's something that did show up in our program material tests.

The Sony BDP-S570 is the fastest Blu-ray player we've tested, beating out even the previous speed champ, the Oppo BDP-83. Part of this is due to the BDP-S570's quick start mode, which allows it to load a disc from the off position over 10 seconds faster than the competing LG players. It's also very quick to load movies with complex menu systems, such "Pirates of the Carribbean." The competing Panasonic DMP-BD80K takes nearly 25 seconds longer to get to the actual movie; the PS3 Slim takes 44 seconds longer. It's a noticeable difference, especially if everyone's anxious to start movie night.
Where the BDP-S570 really shines is our chapter-skip test, where it's nearly twice as fast the Oppo BDP-83. Most other players we've tested sluggishly lurch from chapter to chapter, but the BDP-S570 lets you zip to the chapter you want and it almost instantly starts playing. That might not matter if you're the type of person that tends to watch a movie all the way through, but if you spend a lot of time demoing your favorite scenes, you'll appreciate the BDP-S570's speed.
